And in the beginning the JSF was led by a Marine general with the Marine requirements the priority.
This statement would appear to be flat-out false.

By the time Mike Hough was on board, the requirements were largely set - the JIRD-JORD process was largely complete and the PWSC designs were well under way. You have also stated:
Have the requirements shifted nearly constantly? Yes.
That's also bilge. RP asked you for evidence and you ignored the challenge, because you don't have any evidence. The requirements have remained stable except where they have been relaxed.
